8 weeks today

8 weeks today, trying to stay positive and happy. I had my first scan on Monday. I only have one ovary and tube and get anxious about say ectopic so was nervous. They said all is perfect, baby is 15mm and heartbeat 165. I had worried because my morning sickness reduced suddenly, not that it had been too bad. I hope all continues to go smoothly. Do others deal with anxiety like this and how do you manage?
